Field experience, together with engine laboratory testing, indicated the need for upgrading of Mack's diesel engine lubricant specifications. Field testing and laboratory testing indicated the superiority of several of the newer oil formulations for the Mack engine requirements. The newer type multi-viscosity oils were found to be particularly suited. A modified multi-cylinder engine test (T-5) was developed together with an oil specification based on the use of this test procedure (EO-J).
